Thread-cone support for sewing machines



THREAD-GONE SUPPORT FOR SEWING MACHINES Filed June 26, 1946 INVENTOR. Edward/Vuece @TIE WITNESS Patented Apr. S, 1952 UNITED STATES PATENT OFFICE Edward Muecke, Linden, N. J., assigner to The Singer Manufacturing Company, Elizabeth,

l 1 Claim. 1

This invention relates to a thread cone-holder and more particularly to a cone-holder for use with sewing machines.

The invention has for its object the production of a thread cone-holder from which thread may readily be unwound without producing loops or kinks and in which any spilled thread will be prevented from becoming entangled lwith the support for the cone-holder.

With the above and other objects in view, as will hereinafter appear, the invention comprises the devices, combinations and arrangements of parts hereinafter set forth and illustrated in the accompanying drawings of a preferred embodiment of the invention, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

In the drawings,

Fig. 1 is a side elevation of the partly in section.

Fig. 2 is a sectional plan view substantially on the line\22 of Fig. 1 and Fig. 3 is a detailed elevation of the holding disk cone-holder,

which rigidly retains the cone of thread on the pin and in contact with the base.

Referring to the drawings, I designates a at base-plate provided with a depending lug. 2 apertured to receive a fastening screw 3 and a supporting rod 4 to which the lug 2 is secured and which rod forms a part of a conventional spoolholder (not completely shown).

Rising from the base-plate I is a pin 5 which extends centrally into the cone 6 upon which the thread T is wound, Adjustably secured upon the lower portion of the pin 5, by fastening screw 1, is a holding disk 8 of metal or other relatively hard material, having a threaded periphery; the disk 8 being preferably provided circumferentially thereof with a screw-thread 9 adapted for engagement by the inner surface of the thread-cone 6, thereby to restrain the cone from turning about the pin 5.

The cone 6 is applied to the disk 8 by a slight turning movement of the cone, and the disk 8 is so positioned upon the pin 5 that when the cone is in rigid engagement with the disk the lower end of the cone is in contact with the baseplate I. The lead of the thread 9 is preferably such that the manual turning of thecone to apply it to the disk 8 causes the threads 9 to cut a complemental thread into the inner surface of the cone and forces the cone downwardly into flrm contact with the base-plate I. By thus insuring that the cone is in full pressure contact with the base-plate I, any spilled thread is prevented from accidentally winding about the pin 5.

It will be observed that the metal disk 8 is the sole means for supporting the stationary threadcone 6 upon the pin -5 in cont-act with fixed base I.

Thread drawn from the cone is passed through the eye I0 formed in the downwardly bent end of a thread-guide rod II, which is rigidly secured upon the base-plate I by two collars I2, secured upon the thread-guide rod by fastening screws, as I3. The thread-eye I0 is preferably disposed centrally above the cone of thread T. whereby the thread is unwound from the cone with an even drag.

Having thus set forth the nature of the invention, lwhat I claim herein is:

A stationary thread-cone holder adapted to be secured upon a supporting rod, comprising, a lug apertured to fit upon said rod, securing means for locking said lug in a set position upon said rod, a flat base-plate rigidly mounted upon said lug, a cylindrical pin extending from and disposed normal to said base-plate, a peripherally threaded and centrally apertured disk slidably mounted upon and lengthwise of said pin, the threaded periphery of said disk being adapted to have threaded thereon a soft thread-supporting cone with the thread engagement between the disk and the cone serving to force the bottom end of the cone into pressure contact with said baseplate, and securing means for locking said disk in selective positions of adjustment lengthwise of said pin.
